1.      “Head-On-Hand Music Man” – This technique involves keeping one’s iPod in a front pocket, then stringing the earphone cords up through the torso of a long sleeve shirt, then up the sleeve until the earbuds emerge in the listener’s hand.  The student then rests his head on his hand, seemingly deep in thought while he looks at you as you present your interesting lesson.  You think he is contemplating the difference between acute and obtuse angles, but the reality is that he is listening to 50 Cent.
